What is the difference between using oledbDataReader and DataAdaptor ?
Which one is best to use ? for fetching data from db…
You can use ADO.NET either in a generic style (using the interface definitions), which makes it easier to port your app to a new database, or in a DB-specific form.
If you’re using SQL Server and don’t plan to switch, then it’s usually better to stick with the
SqlClientclasses, such asSqlDataAdapterandSqlDataReader.To fetch from a DB, the best option depends in part on where you want to put the data after you read it.
SqlDataAdapter.Fill()is good forDataSetsorDataTables;SqlDataReaderis good for custom classes.SqlDataReaderis probably a bit faster, but it also does less for you.
